What will youneed

ď‚&#x; A glass filled right to the top

with water ď‚&#x; A piece of cardboard

Gravity Free Water

What's

Happening

What goes up must come down! Right?

Let's see if we can defy the laws of gravity somewhat. You'll need the help of some cardboard and a little bit of air pressure.

Instructions 1.

2.

3.

Put the cardboard over the mouth of the glass, making sure that no air bubbles enter the glass as you hold onto the cardboard.

Turn the glass upside down (over a sink or outside).

Take away your hand that is holding the cardboard.

?

f all goes to plan then the cardboard and water should stay put. Even though the cup of water is upside down the water stays in place, defying gravity! So why is this happening? With no air inside the glass, the air pressure from outside the glass is greater than the pressure of the water inside the glass.

The extra air pressure manages to hold the cardboard in place, keeping you dry and your water where it should be, inside the glass.

Hold the cardboard in place while you turn the glass over. (I have coloured the water green so it is easier to see)Air pressure holds the cardboard against the bottom of the glass.
